Description: MOORA method and the results of its analysis are given. It is shown that the method has some shortcomings which elimination is connected with the necessity of its essential rehash. However its basic idea about comparison of alternatives by two criteria may be used to create a new outranking method – the MOORA-kernel method which will be intended for formation of a core which will contain or one best alternative, or some incomparable alternatives, which are the most perspective for the further analysis. For a new method settlement dependences, and also rules of comparison of alternatives which provide core formation are given. Possibility of practical use of the offered MOORA-kernel method is demonstrated on settlement instances. Comparison of results of the calculations gained by using known and new methods, testifies that use of the MOORA-kernel in a combination with other methods allows to raise validity of developed recommendations or to find perspective alternatives which have not been revealed by other methods. These results allow to draw a conclusion that use of the offered MOORA-kernel method can be perspective enough for multiple criteria optimization of difficult installations.
